TH-D7A (G)
FM Dual Bander
Explore the exciting possibilities of APRS®® with the Data
Communicator — Kenwood’s high-performance TH-D7A (G)
FM dual-band (144MHz/440MHz) handheld transceiver.
Don’t delay. The world of APRS awaits, and
the new Data Communicator is your passport.
APRS (Automatic Packet/Position Reporting System)
To many people APRS suggests the use of a
computer to build a colorful map display of
other APRS operators in your area. You can
thus pinpoint their position and heading, and
exchange text messages. Through the Internet
you can even check operations in areas far
beyond the range of your own equipment. But
the TH-D7A (G) enables APRS operation without
requiring a computer. You can display a friend’s
positional data — including altitude, direction and
distance — using nothing more than the Data
Communicator. And you can use a GPS receiver
to transmit your own coordinates to other members of your group or to anyone using APRS.
■ My Position
If you connect a NMEA-0183 compatible GPS receiver — either NMEA (4800bps) or NMEA96
(9600bps) — the TH-D7A (G) can automatically display your own position data. Included are
current time, speed, heading and altitude. And if you do not have a GPS receiver, no
problem: you can input your position manually (up to 3 locations can be stored for selective
■ Receiving position data
On receipt of data, your TH-D7A (G) pops up the relevant call sign and status text on the
display — in either full-screen mode or together with the frequency (you can now choose
between 2 different interrupt displays). The detailed display includes the station’s type (fixed,
moving, weather, etc.), position comment, icon, grid square locator, direction and distance.
And in the case of a moving station, you can check on its altitude, speed and heading.
Incoming emergency data is indicated by an audible signal and a special screen. (Note: the
data from 40 stations can be stored in memory.)
■ Sending position data
You have control over transmission of your own data to other
stations, determining call sign, icon, position comment (choice of
15), TX interval, and position ambiguity (the last 1~4 digits of your
latitude and longitude can be masked). The options for status text
transmission now include a choice of three types (up to 20 characters each) and a variable rate (once every 1~8 times a beacon is
transmitted, or disabled). Also, the auto TX beacon interval can
now be set as low as 0.2min.
■ Exchanging messages
On receipt of a message, it pops up on screen. A detailed display
identifies message type, call sign, contents, and time passed
since transmission/reception. When you send a message, it is
displayed with such information as line number, status, and time
passed since transmission. A total of 16 messages — sent and
received — can be stored for easy reference. Other messaging features include auto-replay (with separate storage for a message of
up to 45 characters), query packets, and group message reception (up to 6 different group names, max. 9 characters each).
■ Way point position data output (selectable: 6~9 characters) ■ Data band select (cross-band compatible) ■ Packet
path selection with Digipeat ■ Independent selection of
units (i.e. Fahrenheit + meters, Celsius + feet, etc.)

TH-D7A (G)
Everybody’s talking about APRS (Automatic Packet/Position Reporting System), the packet
communications network software that allows Ham radio enthusiasts to transmit and
track coordinates using GPS equipment, laptop computers and even the Internet. Now
available for several platforms, APRS software was originally developed in 1992 by Bob
Bruninga (WB4APR). Offering an easy and intuitive way to transmit positional data and
messages, it has rapidly gained popularity in countries all over the world. And Kenwood’s
Data Communicator is designed to make the most of APRS.
Equipped with a TNC, the TH-D7A (G) provides you with a wide range of data communications
options. But there’s much more: this new model offers greatly improved
performance and features. For example, in addition to your own position data it will now
display current time, speed, heading and altitude. You can also choose from 3 position
memory settings, 3 types of status text for transmission, and 4 data band settings. An
automatic response function is provided, as is a display of time passed since message
transmission/reception. These and many other new features add up to a quantum leap
in convenience.
Kenwood Skycommand System II+
The Sky Command II+ allows you to remotely control the
TS-2000(X) transceiver from a separate location. Since the
TS-2000(X) transceiver has an independent VHF and UHF
sub-receiver in addition to the main transceiver, the subreceiver can work as a “Transporter” without requiring
another VHF/UHF transceiver.
If you already have Kenwood’s TH-D7A handheld or TMD700A mobile transceiver, you can immediately start
enjoying Sky Command II+ features to remotely control
the HF/ 50 MHz band of your TS-2000(X).
You will use one transceiver as a remote control unit,
called a “Commander”. The VHF/ UHF sub-receiver in the
TS-2000(X) transceiver is called the “Transporter”. It will
function as an interface between the Commander and
the HF/ 50 MHz band of the TS-2000(X) main transceiver.
This system allows you, for example, to watch for and
hunt DX while washing your car, or to operate the HF
transceiver while relaxing in your car, living room, or
patio, instead of actually operating inside your shack.
